Median filter is a filter of nonlinear class. This article is a practical guide for understanding and implementation of the filter — it contains theory, C++ source code, programming instructions and sample application. The application demonstrates the capability of the median filter to restore images corrupted by destructive noise. This is not the only kind of corruption the filter can filter out. Download the sample and try this “miracle” of image processing science. Generator of destructive noise and sample image are supplied as well.


That is not so easy to rotate the image in the screen because the screen picture is discrete. So what is the way? One should use special algorithms to calculate antialiased image. This sample demonstrates antialiased image rotation. You can process any 24bit BMP file.


Did you ever interested in question what form had a ball while rebounding from the ground? Do you want to see that? Live mechanics, physics and a bit more. Realtime interactive OpenGL graphics.


This sample demonstrates solving of the problem of optimal control theory. It is pure MatLab calculation sample.


Mean filter, or average filter maybe is the simplest filter of linear class. Nevertheless, it is used widely in signal and image processing, usually as a part of processing pipeline for signal (image) averaging and preparing it for further processing. The article is a practical introduction to this useful tool — it contains theory, C++ source code, programming instructions and sample application for demonstrating filter features.


Filter window, or filter mask is basic concept of signal and image processing. Every digital filter utilizes window idea. The article is close look at this important primitive.

One of the characteristics of ultrasound imaging that limits its application is presence of speckle noise. 3D median filter is used for improving ultrasound voxel image quality and speckle noise reduction.


This MatLab sample demonstrates the ECG processing. Real ECG data and real production processing prototype. Case includes full MatLab source code of the prototype.


Graphics engine is targeted for automotive and industrial embedded devices where graphics performance and quality at low cost is essential requirement.


Due to limited speed of sound it is not possible to get instant 3D shot of the moving objects — while scanning the volume 4D image containing time information as well is got. The case shows technique for 3D animation extraction from 4D volume data.


Modern 3D imaging results in huge graphic data arrays. For transferring these data or storing them their compression is vital point. The case demonstrates 3D volume data compression with the help of 3D wavelet transform.
